Faults along the mountainous Sierra Nevada threaten earthquakes Natural Disasters
Two faults along mountain valleys Carson and Antelope are a danger to people living in the east of the Sierra Nevada.
To study the risk of earthquakes were dug trench depth of 30 to 45 meters. In the Antelope Valley, the scientists found the confirmation of two major earthquakes, accompanied by earthly tears. Rift at 23 kilometers, most likely the result of an earthquake measuring 7.5. Radiocarbon dating of soil samples revealed that the earthquakes occurred in 1350 and 6250 years ago.
Scientists continue to study faults in the Carson Valley. To date, research has helped establish signs of major earthquakes, and data on a small earth movements have not survived.
